so if N37:16 contained the integer 1 and N37:31 contained the integer 5
then N[N37:16]:[N37:31]/14 = N1:5/14

5k has indirect addressing via arrays. it wont translate easily. You could create a data block similar to what you have in 500 using an array, then create your indexing tags.

the syntax is different too. in 5000 that same address would be N[1,5].14
